Every I call someone, the person I'm calling says my voice is garbled if they hear me at all. Is this a common problem with G2's? Any known solutions? Wait for the latest Verizon updates?
The G2 actually has a reputation for excellent call quality, and it's been that way since it was originally introduced. Call quality problems is something that you almost never hear mentioned about the G2.
Try a factory data reset, and if the trouble continues you should see about getting a warranty replacement.
